Thank you for your query.
This sensation is typically caused by either a nerve irritation
or a circulation problem. This will not be caused by a blood clot. The important thing to exclude at her age are metabolic problems, typically diabetes
. This is the first step, to take blood for a sugar and full blood test
. The fist treatment I suggest is to take Folic acid
, Iron and vitamin B12
and B6 supplements as this might be lacking due to her diet.
If there is anything other wrong she will need the help of a doctor and possibly prescription medicine.
I trust this information helps you.
